Development Stage

Early Stage

Focused ultrasound research is in the laboratory phase and is not yet available for patients.

Clinical Trials

Focused ultrasound for this condition is being researched in clinical trials.

International Approval

Focused ultrasound is approved to treat this condition outside the US. Patients can seek commercial treatment at participating international sites.

FDA Approved

The US Food and Drug Administration has approved focus ultrasound for this condition. Patients can seek commercial treatment at participating sites.

Early Stage

Clinical Trials

International

FDA Approved

Focused ultrasound is approved to treat this condition both within and outside the US. Patients can seek commercial treatment at participating sites. There are also clinical trials that may be of interest to patients.

Focused ultrasound is cleared to treat liver tumors in the United States.

The US Food and Drug Administration (FDA) has cleared HistoSonics’ novel therapy platform – called EdisonTM – to treat liver tumors. EdisonTM uses histotripsy to noninvasively destroy tissue in the liver and is the first and only such platform available in the US. This is also the first time the use of histotripsy has earned regulatory approval worldwide. Read More

Focused Ultrasound Therapy

Focused ultrasound is a rapidly evolving, noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with liver tumors. This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the body without damaging surrounding normal tissue.

How it Works
Where the beams converge, focused ultrasound produces several therapeutic effects that are being evaluated.

One mechanism is the production of precise ablation (thermal destruction of tissue). This destruction can be done to completely destroy the target or to partially treat it, and partial treatment is believed to stimulate the patient’s immune response, which may have a broader impact. 

Another mechanism is the use of mechanical (non-thermal) histotripsy to destroy the tumor. 

A third mechanism is to use focused ultrasound to cause hyperthermia which enables the local release and absorption of a therapeutic that is contained in the blood stream. 

A fourth mechanism is to use Boiling Histotripsy to destroy the targets in the liver. This has the advantage that it may be useful as a ‘bridging’ technique to treat the patient and may also help in the regrowth of non-fibrous tissue, as the patient is waiting for a liver transplant. While this has had success in animal models, it has not yet been transferred to human treatment.  

Advantages
The primary options for treatment of liver tumors include surgery, chemotherapy, radiotherapy, localized destruction of the tumor tissue (via radiofrequency ablation, alcohol injection, cryosurgery, or laser photocoagulation), or combination of two or more of these options. The long-term solution for primary liver cancer is often liver transplantation.

For certain patients, focused ultrasound could provide a noninvasive alternative to surgery with less risk of complications – such as surgical wound healing or infection – at a lower cost. It can reach the desired target without damaging surrounding tissue and is repeatable, if necessary. Focused ultrasound can also enhance the chemotherapy dose for the target, with less impact to the rest of the patient. 

Clinical Trials

A clinical trial in the UK is recruiting patients with colorectal cancer and metastasis to the liver. It uses focused ultrasound to activate a microbubble preparation designed to improve the penetration of chemotherapy to the liver.  

An observational clinical trial is being done on patients treated with the Histosonics’ Edison device looking for long term outcomes for the patients treated. 

The Foundation updates these pages regularly, but with the increasing number of clinical trials, we want to be sure that our audience has the latest information available. Therefore, we also added the website search information for the above trials. If you click here, it will take you to the latest information available from https://www.clinicaltrials.gov/.

Regulatory Approval and Reimbursement

In October 2023, the US Food and Drug Administration cleared HistoSonics’ Edison device to noninvasively treat liver tumors using histotripsy. 

A focused ultrasound system has been approved in China, Russia, Europe, and Korea for treatment of liver cancer.

To the best of our knowledge, the use of focused ultrasound to treat liver cancer is not yet widely reimbursed by medical insurance.
